- Application November" 15, 1930 Serial-No. 495x97- j This invention relates to internal coinbustion; engines and more particularly to the treatment of lubricating oil for suchv engines.

It is an object oi my invention to provide irnv proved mearistor regulating the temperature of the t engine lubricating oil. It isknown that lubricating .oil ,for engines vbecomes excessively qhotresulting' in interior lubrication and excesl" sive wear of the 'engine'parts as well as a pre- 1 mature and'breaking down ofwthe oil.

This is especially the case .r conditions I p a a y "A further object of invention resides inimproved means for quickly bringingthe engine oil 'upfto an efficient {viscosity reduced under low temperatures, to thelpointwhere it will not flow efilciently until after considerable .operation of the engine.

"In order to accomplish the objects in view, I have provided, a novel oiLtemperatuIe co'ntrol-' fling device adapted for heatvexchange relation withthe cooling fluid usually water, in the en- 1' For conveniencel have provided a novel ,g pstruction-readily adaptable to engines now in a al bymounting the oil treating device) wil 1? ifi fi a k other 9 -the t vide for heat exchange relationship withthe cool- :59 its a L u b obiectovf myrinvsrition t neans for gfilteringthe oi1.to remove im-" solid particles ofiforeign matl erim equ s h e exchanging w tion, in one" accessory, I have provided @91 'i mrera ll f regulating Sand l r n pf Amy invention w be-apparent iron; the following description of one einbodi nent of my invention as illustratdinfihe) 49 draw n ,gine with my device attached thereto,

, v v lfi onmisl ioiizplea opening intothe jacket structure 11 as shownin Figure 2;

Ajacket cover plate 18 removably-secured at 19f to the cylinder block 10. My oil temperature regulating device'B comprises a relatively long casing 20 suitably sealed againstentrance of water thereinto and-preferably carried by plate 18 by reason of the oilinlet and outlet 7 coupling supports 21 and 22' respectively; Re-

j ierring to Figure 5', I have illustrated one way'inof summer driving which these "couplings may be formed and in which the inner-end'of'oil pipe 23thr'eadedly engages a clamping conduit 24 whereby casing 20 may be firmly removably clamped'with cover 18.

The oil inlet 21 communicates through oil pump 23 and conduit 25 with'the usual oil slflpply'in the crankcase 12 havingtheusualpump-(not shown) for placing the oil throughout. the oiling system including conduit 25' and devic'e B under the desired pressure. From the" device B theoil passes V therefrom by'reason of the outlet 22 and through conduitzfi to the usual engine bearings, surfaces and other'parts usually lubricated (not shown) It is also usually desirable to-provide a conduit 27 between the oil gage '28and conduit 26 to in- ""'dicate the pressure of the oil being supplied to the engine,

The casing Bis suitably constructed to' proing water in theengine and'xIfdo not regard'it necessaryin' order to obtain efiicient'results to for distributing the waterto' thelvariouscylinder I i jac keting"portionsfthe casing having a baflling F 'igure lis an elevation view of ;a typicalene effect permitting" the water to circulate through spaces 29, 301and 31 exteriorly or casing20.

7 Within casing 20 I preferably provide means for suitably cleaningor'filtering the oil. To this end a I r H i 7 a plurality of fine mesh screening forming a filter Figure 3 is a verticalsectional view through my unit 32 is provided whereby the oil is filtered as manner of arranging the screening is to provide relatively coarse screening at thebottom of the filter unit 32 and relatively finer screening toward the top. I also have provided the casing lower wall 33' with a deflectedftap'ering rib 34 forming 'a seat for the unit 32 whereby theunit 32 is spaced from the lower wall 33 t0 form oil channels 35. The incoming oilirom conduit 23 v is distributed along channels35 and thence passes upwardly through the filtering unit to outlet channels 35 formed similarly to channels. 35

by reason of the tapering rib 34 'formed in the upper wall'33 The tapering ribs 34 and 34 provide for'efflcient distribution of the oil relative tothe inlet and outlet. 7 By reason'of my invention the oil inpassing from the crankcase to the engine is first treated by the device B. For summer driving the device B serves to cool'the oil by reason of the heat ex% change relation with the jacket cooling water.

For winter driving and in starting the engine, the oil "temperature is quickly raisedto' substan-' tially the water temperature. In" many automotive vehicles the cooling water is controlled.

as to its temperature by thermostatic circulation control or radiator shutters whereby the cooling water is quickly brought "up to eificient temperature. My invention provides an improved ,-;means for maintaining the oil atsubstantially uniform temperature, the engine and oil under such conditions lasting longer, providingimproved lubricating action in-general, minimizing oil consumption and enabling the oilto be used longer customary.
